Reassessing the Influence of Party Groups on Individual Members of the European Parliament

This paper reassesses the way in which the voting behaviour of individual members of the European Parliament (EP) is influenced by their national and European party delegations. It does so within the previously used framework of one agent with two principals. First, it shows that the previous literature was unable to fully fathom the mechanisms through which the tripartite principal–agent relationship works. Second, it develops a model that looks solely at the votes contested between the European and the national group and the results of the test correct many of the findings of the previous literature. The paper also develops a new theoretical framework of vote cohesion in which the national and European groups are motivated by group norms and external incentives. Finally, the analysis of roll-call votes from the sixth EP finds that the new members from Central and Eastern Europe are more likely to stay with their European group than the members from Western Europe.     

Allelic frequencies and statistical data obtained from 48 AIM INDEL loci in an admixed population from the Brazilian Amazon

Allelic frequencies of 48 informative insert-delete (INDEL) loci were obtained from a sample set of 130 unrelated individuals living in Macapá, a city located in the northern Amazon region, in Brazil. The values of heterozygosity (H), polymorphic information content (PIC), power of discrimination (PD), power of exclusion (PE), matching probability (MP) and typical paternity index (TPI) were calculated and showed the forensic efficiency of these genetic markers. Based on the allele frequency obtained for the population of Macapá, we estimated an interethnic admixture for the three parental groups (European, Native American and African) of, respectively, 50%, 21% and 29%. Comparing these allele frequencies with those of other Brazilian populations and the parental populations, statistically significant distances were found. The interpopulation genetic distance (F_ST coefficients) to the present database ranged from F_ST = 0.0431 (p < 0.00001) between Macapá and Belém to F_ST = 0.266 (p < 0.00001) between Macapá and the Native American group.
